  • Angle adjustment apparatus for electronic device
    Patent number: 7618017
    Abstract: An angle adjustment apparatus for an electronic device according to the present invention can be inexpensively formed by a compact and simple structure and readily assembled and disassembled. When a telephone set as an electronic device is in a small inclination position, auxiliary plates are substantially in parallel to supports of a leg. Tips of the auxiliary plates are brought into abutment against right surfaces of the first projections. Click portions of the supports are brought into abutment against left surfaces of the second projections. Accordingly, the supports cannot be further rotated counterclockwise with respect to the base. When the telephone set is in a large inclination position, the auxiliary plates are perpendicular to the supports. The tips of the auxiliary plates are brought into abutment against the engagement portions of the base. The click portions of the supports are located between the first projections and the second projections.
